Abstract

Headphone eartips with internal support components and methods for making the same are provided. Different support components may provide specific amounts and types of additional rigidity at specific portions of an exterior surface of an outer eartip body that may be expected to interface with specific portions of an ear canal geometry when an eartip subassembly is positioned within the ear canal, such that the eartip subassembly may conform to the various shapes of the ear canal while maintaining an acoustic seal.
